Paying what you really owe is the idea behind Equipay, a satirical take on structural and historical inequalities, especially regarding race and gender. Winner of Cultivated Wit's Comedy Hack Day, Equipay will be available to the public in March.

"Equipay helps you avoid the entrenched discrimination that exists in our society," the app's website says. "It doesn't split the bill equally—it splits it equitably. You pay what you should to balance out the wage gap."

The app pulls data from the US Bureau of Labor Statistics, allowing a group of diners from disparate backgrounds to split the cost of a restaurant bill "in accordance with gender and racial income inequalities," the creators say.
